Abstract
Originally new to provide a kind of convenient additional type lifter, it includes：Spool assembly and 2 bearings, spool assembly both ends are installed on 2 bearings respectively；Be provided with the spool assembly it is more than one can not rotary part, it is described can not rotary part be fixedly arranged on bearing so that can not rotary part do not relatively rotated with bearing；It is characterized in that：It is described that a normally opened clutch can not be provided between rotary part and fixed bearing, during so that normally opened clutch being in open state, can not rotary part can be relatively rotated with fixed bearing, spool assembly internally-powered system no longer spool is played power drive effect.Therefore when the motor in spool assembly, gearbox or other power parts or transmission parts can not normal work when, can be by opening normally opened clutch, to be rotated using emergency power mechanism or external connection power mechanism driving spool assembly, then driving door curtain up or down row at any time is realized, the problem of to overcome traditional like product to need violence to dismount.
Description
Technical field
This is new to be related to outside one kind and installs lifter additional, especially sets and the outer installation lifter of door roller.
Background technology
Traditional rolling door motor and tube shaped electric machine all have to the adhesive with electromagnet, disengage principle to carry out axial brake
Car.Magnet coil burns, short circuit or brake disc nut come off situations such as blocking when occurring, and door curtain hovers in residing position at that time simultaneously
Put, because dismounting inconvenience can only solve the problems, such as by destructive dismounting, therefore easily badly damaged door curtain or other parts,
Cause many waste products.
In addition when motor breaks down, block or electric shift mechanism breaks down, it can all cause system stuck.
Furthermore conventional motors must have a supporting plate, driving chain, what ratchet etc. was driven；Installation is complicated, loaded down with trivial details, wave
It is time-consuming, manpower and materials etc.；Space-consuming is big, it has not been convenient in box etc..
Last traditional supporting plate has to other instruments such as electric welding machine, angle bar and is fixed, and real work condition is harsh.
The content of the invention
In order to overcome above mentioned problem, this is new, which to provide, a kind of does not have the braking mechanism such as electromagnet, coil and can at any time all
The outer installation door roller jacking system that can be risen or fallen.
To achieve the above object, the technical scheme of this new offer is：
A kind of convenient additional type lifter, the lifter are provided with a fixing end, and the fixing end is provided with more than one
Actuating unit, the output end of actuating unit connects the input shaft of a gearbox；The output end of the gearbox is provided with spool
Driving wheel.
The lifter is provided with a normally opened clutch, and the normally opened clutch is located on gearbox or actuating unit
On so that when normally opened clutch is in closed state, the output shaft of gearbox can not rotate.
The normally opened clutch is a worm and gear, the actuating unit drive connection worm gear, and the worm drive connects
Scoop out the input of anxious gearbox.
The normally opened clutch can also use following scheme, and the normally opened clutch includes brake press plate, ratchet
Chain is pulled with ratchet；One movable end of the brake press plate, which relies on, to be pulled on chain, and a movable end relies on spine
Between two teeth of wheel, ratchet is set not rotate；The chain departs from the torque of ratchet to the torque direction of ratchet with brake press plate
Direction is identical, when pulling chain, brake press plate can be made to leave the limitation to ratchet.
The actuating unit is motor, pulls one of ratchet and rocking bar or be wherein combined.
Above-mentioned technical proposal is beneficial in that：
1st, it is originally new to be applicable to any conventional rolling door motor, including tube shaped electric machine and plug-in motor, first by lifter
It is installed in spool, and fixing end is installed on attached support；Freely turn because under default conditions, the output shaft of gearbox is in
Dynamic state, has no effect on any control of spool；And when motor in spool or plug-in motor break down, it can use and rise
The actuating unit of device or the output shaft rotation of external connection power mechanism driving gearbox are dropped, then realizes driving door curtain up or down at any time
OK, the problem of then overcoming traditional like product to need violence to dismount.
2nd, this is new due to using normally opened clutch, can carry out control for brake random to door roller.
It is further introduced by the following examples with reference to accompanying drawing to originally new.

Embodiment 2
As shown in figure 4, a kind of convenient additional type lifter of embodiment 1, described arrestment mechanism include brake press plate 31 ' and
Chain 2 ' is pulled on ratchet 1 ', a movable end 32 ' of the brake press plate 31 ', which relies on, to be pulled on the bar of chain 2 ', one
Movable end 33 ' stretches into the between cog of ratchet 1 ' so that under default location, ratchet 1 ' is not rotated；The chain 2 ' is to spine
The torque direction of wheel 1 ' is identical to the torque direction of ratchet 1 ' with brake press plate 31 ', when pulling chain 2 ', can make brake press plate
31 ' leave the limitation to ratchet 1 '.
Principle is：When not extraneous power supply, can by pulling the pulling of chain 1 ', departing from brake press plate 31 ' with
Between cog engages on ratchet 2 '；Drive ratchet 2 ' to operate simultaneously, band tooth is pulled the rotation of axle 3 '.The rotation of axle 3 ' is pulled with tooth, is passed
Pass the operating of primary planet pinion 4 '；Primary planet carrier 5 ' has also been driven to rotate simultaneously；Gu primary planet idler gear 6 ' is driven,
Operation, and driven secondary planetary gear 7 ' to rotate；Similarly also with secondary planet frame 8 '（Secondary planet frame is called defeated manually
Shaft 8 '）Output rotates.
Gearbox in above-mentioned two embodiment is combined by two-stage or two-stage above gear ratio, gearratio
It is to be determined according to the gravimetric value of door curtain 47, calculates.
Chain is pulled as long as pulling --- -- having driven hand pull mechanism operation ----drive hand gear transmission mechanism to transport
Turn --- --- while pull output shaft and driven driving wheel, spool, door curtain to run together.
Motor is heavy-duty motor during above-mentioned two is implemented, and can lift each of 400kg ~ 1500kg door curtains or weight
Kind motor.And tube shaped electric machine is all low-power machine at present, curtain or small garage are all used in.
Above-mentioned two embodiment lifter can be used as fire resisting shutter door roller, and it reaches GA603-2006《Fireproof rolling
Curtain door roller》；CNCA-C18-02：2014《Compulsory Certification of Products code fo practice fire protection product》；CCCF-HZFH-02
《Compulsory Certification of Products detailed rules for the implementation fire protection product building fire resistant element product》Test stone.
Examine project outward appearance and parts, basic performance, mechanical life, power source performance, insulating properties, pressure-resistant performance,
The requirement of the standards such as weatherability environmental performance.
It is pointed out that the just transmission door roller system of above-described embodiment and the record with being not new to this
The limitation of type protection domain, as long as the technology that usage right requirement 1 is recorded, in this new protection domain.
In summary some, this additional type riser structure uniqueness, saves many human resources, it is not necessary to waste etc. one
It is daily a bit to be cracked in the absence of the rule having.It will be, the most direct Novel electric most advanced in industry that rise to conventional motors
Machine.It is a kind of high-tech content highest New-type electric machine, dominates the innovation strength of whole industry.
